[BUG] kompose crashes on simple docker-compose.yml with name: top-level element

### Expected Behavior

I was testing `kompose` (installed via Ubuntu 24 snap); the program doesn't show any version information.

I'm using the example from the [docker documentation](https://docs.docker.com/reference/compose-file/version-and-name/#name-top-level-element):
```
$ cat docker-compose.yml
name: myapp

services:
foo:
image: busybox
command: echo "I'm running ${COMPOSE_PROJECT_NAME}"
```

which results in
```
$ kompose convert -f docker-compose.yml -o k8s
ERRO Could not parse config for project test : yaml: unmarshal errors:
line 1: cannot unmarshal !!str `myapp` into config.RawService
FATA composeObject.Parse() failed, Failed to load compose file: yaml: unmarshal errors:
line 1: cannot unmarshal !!str `myapp` into config.RawService
```

Removing the `name` and the reference to `COMPOSE_PROJECT_NAME` results in:
```
ERRO Could not parse config for project test : Unsupported config option for services service: 'foo'
FATA composeObject.Parse() failed, Failed to load compose file: Unsupported config option for services service: 'foo'
```

Running the docker-compose through `docker compose config` also fails.

### Actual Behavior

It should handle at least simple examples from the docker compose documentation correctly. ChatGPT recommended kompose, but so far it failed on all examples I tried.

### Steps To Reproduce

_No response_

### Kompose Version

```Text
1.21.0 (992df58d8)
```

### Docker-Compose file

```YAML
name: myapp

services:
foo:
image: busybox
command: echo "I'm running ${COMPOSE_PROJECT_NAME}"
```

### Anything else?

Start by reproducing the failure with the provided docker-compose.yml using `kompose convert -f docker-compose.yml -o k8s`, then trace the `composeObject.Parse()` configuration-loading path named in the error. Done means the documented `name` and `services` example parses successfully and converts to Kubernetes output without the reported unmarshalling or unsupported-option errors.
